音高的优势区域（DR）被确定为16-和200-ms的复杂的音调，包含250 Hz的基频（170）的前七个谐波。一个音调呈现为其中一个谐波向上或向下失谐3%，500 ms后呈现为相同持续时间的完美谐波音调。听众调整了和声的F0，使其音调与失调的复合音的音调相匹配。在实验1中，刺激单耳呈现。短持续时间的DR谐波数显著高于长持续时间。由所有谐波产生的音高偏移的总和对于短持续时间比对于长持续时间显著更大，推测是由于前者的更强的感知融合。在实验2中，失谐谐波只呈现对侧的复杂的其余部分。在DR与持续时间观察到类似的转变，虽然音高的变化小于单耳介绍。持续时间对整体音高变化没有显著影响。结果进行了讨论，在模式识别和自相关模型的音高感知，并在音高匹配的注意力的作用。(c)2005年美国声学学会。
The dominance region (DR) for pitch was determined for 16- and 200-ms complex tones containing the first seven harmonics of a fundamental frequency (170) of 250 Hz. A tone was presented with one of the harmonics mistuned upwards or downwards by 3%, followed 500 ms later by a perfectly harmonic tone of the same duration. Listeners adjusted the F0 of the harmonic tone so that its pitch matched that of the mistuned complex. In experiment 1, stimuli were presented monaurally. The DR was significantly higher in harmonic number for the short than for the long duration. The overall sum of the pitch shifts produced by all harmonics was significantly larger for the short than for the long duration, presumably due to stronger perceptual fusion for the former. In experiment 2, the mistuned harmonic was presented only contralaterally to the remainder of the complex. A similar shift in the DR with duration was observed, although the pitch shifts were smaller than for monaural presentation. There was no significant effect of duration on the overall pitch shifts. The results are discussed in terms of pattern recognition and autocorrelation models of pitch perception, and a role of attention in pitch matching is suggested.
